When Was the Wonder Created:
604-562 BC

Robert Koldeway began excavating the ruins in 1899. Greek historians such as Berossus and Diodorus Siculus have the most descriptive accounts of the Gardens. Other Greek writings of Strabo and Philo of Byzantium reveal additional details of the wonder.

What is the Location of the Wonder:
The exact location of the Hanging Gardens is in dispute, but in general, they existed on the
East bank of the Euphrates River,
Babylon. On today's map, 50 kilometers south of Baghdad, Iraq

Does The Wonder Still Exist?
The Hanging Gardens do not still exist. There are ruins that are believed to be the structure on which the gardens stood.

Does the Wonder Attract Tourism?
The ruins of Babylon are a popular tourist destination, but due to the uncertainty surrounding the Gardens, there is no specific industry surrounding this wonder. Much of the building material that made up the city of Babylon has been quarried away for use in other buildings, so what does remain of this great city, is usually just the lower sections of structures and foundations.

Who Made The Wonder?
The ruler Nebuchadnezzar II ordered the gardens construction

Why Was the Wonder Made?
They were made to please Nebuchadnezzar's homesick wife, Amyitits, who was from Media, a green and mountainous land.

Other Information:

The Hanging Gardens of Babylon didn't actually 'hang.' They were a built atop terraced roofs high in the air .

In a barren region, Nebuchadnezzar succeeded where nature had failed. The gardens were made to look like a natural Median wilderness. Nebuchadnezzar had man made hills covered with many different types of trees, which satisfied his wife's passion for mountainous surroundings. The gardens were sloped down like a hillside, and were also terraced into different flowerbeds. The beautiful landscape of the Hanging Gardens helped make it a special structure, and transformed the desert-like environment into a pastoral countryside.

The gardens formed a quadrilateral shape. There were stairways that led to the uppermost terraced roofs. The plants hung over terraces that were supported by stone columns. There were arched vaults, which were located on cubed fountains. The fountains created a humidity that helped keep the area cool. The shade from the trees also helped keep the gardens cool. The garden ascended in closely planted levels to form a man-made replica of mountain greenery. The gardens were supported by an intricate structure of stone pillars, brick walls, and palm tree trunk beams. These trunks were made watertight.

The gardens were as much of a technological feat as they were an architectural triumph. The technique of hydro engineering demonstrated their knowledge of irrigation. Since Babylon rarely received rain, the gardens had to be irrigated. Streams of water emerged from elevated sources and flowed down the inclined channels. This kept the whole area moist and thus the grass was always green.
